This change adds support for ACPI devices that use ExclusiveAndWake or SharedAndWake in their _CRS GpioInt definition (instead of using _PRW), and also provide power resources. Previously the ACPI subsystem had no idea if the device had a wake capable interrupt armed. This resulted in the ACPI device PM system placing the device into D3Cold, and thus cutting power to the device. With this change we will now query the _S0W method to figure out the appropriate wake capable D-state. Signed-off-by: Raul E Rangel <rrangel@chromium.org> Signed-off-by: Rafael J.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
